Abstract:Nanoparticle and nanostructured coating synthesis is commonly hampered by complex processes or the need to use precursors which may not yet be registered under TSCA or REACH. There are, however, simple and practical processes using conventional equipment and raw materials that can be safe, economic and cost-effective. This review is illustrated by the authors’ experience of scaling a range of metals, ceramics, oxides and non-oxides using a range of synthesis methods including microwave, combustion synthesis, milling, plasma and freeze drying.
